Product details
Overview
SMB10J17A-M3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 17 V stand-off voltage (VWM), 18.9–20.9 V breakdown voltage (VBR) at 1 mA, 27.6 V clamping voltage (VC) at 36.2 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMB10J17A-M3/52 datasheet, SMB10J17A-M3/52 pinout, SMB10J17A-M3/52 application, or SMB10J17A-M3/52 equivalent, key selection criteria include clamping performance under 36.2 A surge, unidirectional polarity for DC-biased protection, AEC-Q101 qualification status, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a silicon avalanche device with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to limit transient overvoltages before they damage downstream ICs or MOSFETs. Its unidirectional configuration enables use on positive-rail protection without reverse-bias leakage concerns beyond 1.0 µA at 17 V.
The SMB10J17A-M3/52 is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation in automotive engine control units and industrial motor drives where ambient temperatures exceed 85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A-M3/52 | Same VWM (17 V), identical SMB package, but lower PPPM = 600 W and VC = 27.6 V @ 21.7 A. | Lower surge capacity limits use to less severe environments (e.g., consumer-grade power supplies). | Select when cost sensitivity outweighs need for 1000 W surge margin and system-level IEC 61000-4-5 compliance is not required. |
| SMCJ17A-M3/52 | Same VWM and VBR, but SMC (DO-214AB) package with 7.11 mm width and 2000 W PPPM. | Larger footprint and higher surge rating suit high-reliability industrial inverters and solar charge controllers. | Choose when board space permits larger package and system requires >1000 W surge handling with same clamping behavior. |
Compared with SMBJ17A-M3/52 and SMCJ17A-M3/52, the SMB10J17A-M3/52 delivers optimal balance of 1000 W surge capability, SMB footprint constraints, and AEC-Q101 qualification-making it the preferred choice for automotive and industrial designs requiring validated reliability without board area penalty.

FAQ
What is the clamping voltage of SMB10J17A-M3/52 at its rated peak pulse current?
The SMB10J17A-M3/52 has a maximum clamping voltage (VC) of 27.6 V when subjected to its rated peak pulse current of 36.2 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J17A-M3/52 maintains this clamping performance across its specified operating temperature range.
Is SMB10J17A-M3/52 qualified for automotive applications?
Yes, SMB10J17A-M3/52 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including engine control, body electronics, and ADAS modules. The "M3" suffix indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance requirements. The SMB10J17A-M3/52 undergoes stress testing per AEC-Q101 including HTGB, HTRB, and temperature cycling.
What is the difference between SMB10J17A-M3/52 and SMBJ17A-M3/52?
The SMB10J17A-M3/52 offers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ17A-M3/52, with identical VWM (17 V) and VC (27.6 V) but higher IPPM (36.2 A vs. 21.7 A). Both use the SMB package and M3 halogen-free finish. The SMB10J17A-M3/52 is intended for more demanding surge environments such as automotive load dump, while SMBJ17A-M3/52 targets lighter-duty applications.
Does SMB10J17A-M3/52 have polarity marking, and how is it identified?
Yes, SMB10J17A-M3/52 is unidirectional and features a cathode band (color stripe) on the body indicating the cathode terminal. The anode is the opposite end. This marking aligns with DO-214AA mechanical standards and ensures correct orientation during PCB assembly. Polarity must be observed to prevent forward conduction during normal operation; reverse connection would cause short-circuit behavior.
What is the thermal resistance of SMB10J17A-M3/52, and how does it affect PCB layout?
The SMB10J17A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, PCB layout must provide adequate copper area and thermal vias-especially critical in automotive under-hood applications where ambient exceeds 85 °C. The SMB10J17A-M3/52 thermal data assumes this minimum pad size.
